The double sticky trap (DST) is described for the first time and is evaluated along with standard ovitraps and sticky traps (STs) to determine population densities of Ae. aegypti in the urban township of St. Augustine and the rural community of Tamana, Trinidad, West Indies. Ten houses were selected at each study site. At each of the ten houses, one ovitrap, one ST, and one DST were placed using the criteria established for placement of ovitraps. The results showed the three trapping methods successfully collected Ae. aegypti mosquitoes. All three traps collected significantly more adults or eggs in St. Augustine than in Tamana. DSTs collected 2,286 adults from St. Augustine vs 316 adults from Tamana (p<0.002), STs collected 1,480 and 220 adults, respectively (p<0.01), and the ovitraps collected 2,735 and 517 eggs, respectively from St. Augustine and Tamana (p<0.002). Based on these results, the DSTs collected significantly (P<0.02) more adults than the STs. The DSTs and STs collected both adult and immature stages which can be used for toxicology, virology, and PCR studies and are suitable alternative Ae. aegypti surveillance tools for the Caribbean and Latin American region.
